Bultaco Bandit El Montadero 360

Re: The Count Mount Zeke's El Montadero 360

Yes, but not rolock.
They work great on steel but I think they could put grooves in alloy unless your real careful.
DA is probably the best bet for large flat area's but I haven't found anything that works in the tight corners.
Most professional polishers would use a soft cotton mop on buffer.
You use layers of glue and emery powder then crack the solid mass so it's stuck to the ends of cotton threads.(making something similar but with thousands of 'strands' instead of a few hundred)
Don't know if it's even possible to get the stuff to do that nowadays?
I did buy the water based emery compounds from Eastwood, didn't like it much so cut it into slices, soaked in water then made 'mud' to coat mops.
Doesn't stick as well as the glue/emery did but works OK and doesn't groove things
$57.50 each for them is just way OTT, you know what I would do

Have a friend who uses a tootsie roll on a die grinder for the tight spots and then a da for the rest. Zeke pinned me down saying he knew there was a better way to do it.

We have watched the guys who polish the semi truck tanks and wheels and they were doing what you said and they used a rake to get the balls on the end of the cotton mop. Have you ever seen them use a rake on a bench polisher on the cotton mop like they do on the big hand held polisher? I will post the video.

I watched the same polishing video. I heard those roloc discs have silicon oxide and are quite abrasive, too much for poor aluminium.

Re: The Count Mount Zeke's El Montadero 360

The Spanish aluminum Bultaco cases seem quite a bit lighter.(and softer) than the Honda aluminum cases. (Maybe more pure aluminum?) Gonna weigh a couple today for comparison. I like the d/a for safety sake. We got our first da and angle die grinder from HF yesterday we are gonna try different size pads and see what works the best. The polishing wheel was amazing the first time we used it on Victoria's cases we did Lucky's cases with the Meguiers drill polishing pad that took forever. Trying to get all the fabrication into one area that Zeke has a habit like wearing a respirator... The challenge is the economy of space. I like the idea of having three rolls of paper discs mounted above the bench 320, 400, 600. When you are finished it goes in the trash.

Those are nice. Every now and then Kop says something smart.

That's the type I've used. Work well but you will need finer grits to polish aluminium.
The 100 grit I used on steel did a great job, I would think 240 and 320 would be lowest grit numbers to use

Zeke did the chain guard with a D/A 200/320/400/600 polished

Re: The Count Mount Zeke's El Montadero 360

Did a nice job! When it comes to getting a finish on aluminum I used to be one of the crazy sanding guys, even going to 5000 grit at times (this was for when I needed an unbelievable show finish on the telescopes I restored). Nowadays I've become a big fan of using a wide range of compounds with a few different rpm bench top wheels. If a piece is real rough I will use a real gritty one and a 3600 rpm wheel to start. Only drawback with that speed is it's hard to keep the wheel primed, really runs through compound. Generally though I can use 3-4 compounds (different wheels for each of course) and finish with a polish. I feel like it gets me 95% if what I got with all the sanding in a small fraction of the time. I've used the same process on copper plated stuff also, and got excellent results. I'm all about fine tuning to save time! ;D

The Count Mount Zeke's El Montadero 360

We had some new parts come in for our Bultaco Montadero's. Tim of Bultaco.com sent us a few extra steel clutch plates so we could make a tool to hold the right side of the engine to torque the nut correctly. We also picked up a piston stop vernier gage and some angled feeler gages. If you ever try to set the points gap on a Bultaco you will know why these are necessary.,

Hugh of Hugh's Bultaco told us some great info about our bikes. he use to race a detuned bandido. He said he used a 30mm carb and heavier piston with a longer skirt and whooped the field and had a blast.

I also asked him about the relationship between the bandido platform and the TSS Road bike. He said the TSS350 and the Bandido share the same platform but the TSS had a 5 speed gear box vs the Bandido's 4 speed. He also said the Bandido with the right gearing 4 speed will hit 96mph easy on a dirt bike. The TSS 350 also had more ports in the rear of the cylinder and piston.

So I did a little more research after hanging up with Hugh and found this jewel. The 1969 TSS 360 Prototype. It has a 250 TSS Frame with a modified Bultaco Bandido engine married to a 5 speed transmission. It won the 24 Spanish Endurance Road Race Mountjuic beating the more powerful 4 strokes with 50bhp and a top speed of 135 ish. We also learned about another father son team Frank and Barry Sheene

Re: The Count Mount Zeke's El Montadero 360

Why develop a new platform, race it, win, then abandon it? Was the tz and TD yamaha that good? Was there no improvement for the piston port? Was the reed design so much better? Bultaco tries to develop the reed and then abandons it...

The Bultaco 360 M141 Prototype

"The Montjuic project was developed over a long period of time and should have been Bultaco's flagship in the road bike segment."

Re: The Count Mount Zeke's El Montadero 360

Maybe we will do something in the future like drop the Montadero in a road racing frame. 1.5 ton may be a goal but that would take a five speed or some taller gearing.

picture of the Bultaco top dead center gage. With mm on the plunger. Probably can do the same thing with a spark plug, pencil and rubber band.

56.99 including shipping. We are still prepping both tanks. It is all in the prep..
We used Red Kote on another tank it works well with unleaded fuel only. But we want to run leaded race fuels in the Bultaco's.
