Re: Hard Time's build diary
no, if the blades clogging up, i'd say use a bigger toothed blade, any plastic material you cut with jigsaw will melt because of the heat, you can use lubricant but i'd just smooth off any roughness with a file after or if it was melting badly i'd just take it slow
but thats just me, personally im lazy and like to keep things clean where i can to save myself more time spent cleaning up lol
Re: Hard Time's build diary
just to clarify a metal blade will have smaller teeth than one for wood
Re: Hard Time's build diary
I have a table saw which works a treat on HDPE and aluminium (proper blades a must!!) and have seen jonno using a circular saw on polycarb, tends not to clog up as the teeth are much bigger
Re: Hard Time's build diary
I used a circlur saw, which worked.
Re: Hard Time's build diary
holding the poly carb when circular sawing it isn't pleasant, large chunks of poly c at high speed hitting you all over :crazy:
Re: Hard Time's build diary
Don't forget to have the jigsaw running at a low speed. This will reduce (although not eradicate) heat generated during the cutting process. I find a coarse blade (bigger teeth) to be best, as has been mentioned. Don't force the jigsaw through the material, just take it at a steady pace and it will be fine. It should fly through 6mm HDPE and will also be pretty quick through the 15mm stuff.
I wouldn't bother too much with coolant for it; if you keep the speed down (maybe setting number 3, if your jigsaw goes from 1 to 6) and take it steady it will cut without issue.
Re: Hard Time's build diary
got a bench saw and cut the Hdpe today tomorow cutting the top and bottom and uploading pics of what my robot will look like.
Re: Hard Time's build diary
Re: Hard Time's build diary
Yeah it's gonna beat yours!!! Havent cut the rest of plastic yet because a)I've had loads of homework b)becaus eI have to use the bench saw outside and because of rain I cant (humph(angry)). Hopefully getting the plastic cut soon.
Re: Hard Time's build diary
mine will easly beat yours, for a start my robot has 2x the amout of pushing power, thicker armour and a better driver. lol :mrgreen:
