2zwudz Posted February 19, 2020 Posted February 19, 2020 What do you guys use for blower drive belts on your drag engines??? thanks mark
PHPaul Posted February 19, 2020 Posted February 19, 2020 No direct experience, but I have some VERY tiny cog belts from scrapping old printers that might well work.
Claude Thibodeau Posted February 19, 2020 Posted February 19, 2020 Hi! One item that may do is a cheap latex party balloon, available in black at the Dollar store. You take sharp scissors, and cut a 1/16" wide section of the "neck" of said balloon. Since it is thin, rubbery, black, and stretchable, you can then wrap it around your upper and lower pulleys. Granted there is no cogs on the inner side of this "belt", but the very thin "rubber" is in scale to a 1/24 or 1/25 engine. For what it costs, you may try it... CT
1320wayne Posted February 19, 2020 Posted February 19, 2020 Certain vacum cleaner belts are useable. Some are thin enough and they are cogged so they represent better than flat rubber or electrical tape.

Ripped apart a dead battery powered carpet sweeper a month or two ago just to see what was inside it. I'd put the scale for the belt in it at maybe 16th or 12th scale, though.

Daddyfink Posted February 20, 2020 Posted February 20, 2020 Black painted masking tape. Yup, it looks fine!

I've cut black vinyl tape into a strip, and then run it around the pulleys two or three thicknesses until it looked good. The cogs could be added if desired by cutting some Evergreen strips into pieces and sticking them on the inside surface of the tape, but I'm not sure the improved looks would be worth the amount of tedious work that would be involved.
Claude Thibodeau Posted February 20, 2020 Posted February 20, 2020 Hi! Just to add to the vacuum cleanerbelt idea... The smallest cog belts I've seen came from VHS cart machines. But still a tad too big for 1/24, as indicated above. CT

Adding cogs is just way more than needed. Even on a contest model, the tape by itself looks good. Using the belts out of VCR's or the like are just too much. The scale is way off and they look silly in the end.

Impalow Posted February 20, 2020 Posted February 20, 2020 (edited) Ive been using printed paper.... 2peices glued together... one side a solid color, the other side gray and black lines.. then darken the edge with a sharpie.... it seems to work pretty good! Same trick for a modern timing belt.... Edited February 20, 2020 by Impalow

Safire6 Posted February 21, 2020 Posted February 21, 2020 I wish this thread was around 3 or 4 weeks ago! I just finished building the engine for the Tony Nancy 1:16 front engine dragster. The black rubber "belt" that came with the kit was a little to small to fit over the pulleys I thought. It looked like if I used the belt that came with the kit, it would put too much stress on the plastic part and something would surely break. So I carefully tried stretching the belt out with my fingers, a little at a time. Of course I stretched it too much and it snapped. OK now what do I do? I thought that maybe I could use a bicycle inner tube and cut a thin section out of it, IF I could find the right size. So I calculated the inner tube diameter that I needed and went to the local bike shop. I got lucky and found almost exactly the tube diameter needed to make the belt, with about a 5% stretch. it took me about 4 tries cutting thin sections out of the inner tube to get one that looked acceptable. At about $6 for the inner tube, this was not a cheap blower belt! But if I ever need one that size again I'll be able to make hundreds of them!

The thickness is in scale with the engine. Bravo! CT

I'm specially impressed by the sheen of your engine parts. Is-this paint? Your chassis looks like the finish we can obtain from Krylon's Premium Classic Crhome spray can, but I might be wrong... Bravo! CT

In hindsight, should have been much more clear... I just print regular old copy paper on my inkjet printer with the image below, spray it with some krylon matte clear to seal it up and create a bit of sheen. Then I print another block of color the same size (black in this case) I also seal this up with some matte clear. I then use regular old spray mount to stick these 2 pieces of paper together printed side out. Then just cut strips to the width I need, wrap it around the pulleys, overlap and join it at a inconspicuous location with a dab of glue... usually at the bottom of the crank pulley. 42 minutes ago, Claude Thibodeau said: Hi Eric!

That is the Bubbletop Comet showrod I did a few years back... here is a link to the build log. http://www.modelcarsmag.com/forums/topic/127669-moebius-comet-wild-bubbletop-show-rod-done-3-17/ All of the chrome on this is airbrushed molotow chrome, with spazstik's clear... the clear dulled the chrome effect a bunch in places, but made it able to be handled, the sheen is interesting.

Hi! Thanks for sharing your technique. Much appreciated. I like to learn from the best! This show rod creation is mindblowing, truly. Imaginative, and perfectly executed. Bravo. I've never tried spraying the molotow chrome myself. Used mostly Alclad. However, I've started spraying it over gloss WHITE or LIGHT BLUE instead of the usual black. On the white, it creates a sheen akin to real polished aluminium. See the Duster ProMod engine below. I'll ultimately try your technique, however... CT

This^....... one printer yields quite a bit of belt material and it looks imo very real in 1/25 scale
