replacing lower Mark 5 belt with common automotive belt
I need to replace the lower belt on my shopsmith. Being a cheapskate and impatient, I figured I might be able to go to a local lawnmower shop and pick a belt up without waiting for shipping, or paying 19.95 plus shipping for it. I'm sure others have done/attempted this. Any advise against it? Anyone know the size? Thanks in advance.

Doubt you will find one.
Get one from the mother ship.

Use a link belt. Others have done that and report quieter operation and less vibration. Let us know if it works.

Umm are you serious? I assume you are. Now is there something I am missing. The link belts I am familiar with are flat. For example I am looking at replacing the v belt system on my table saw with a link belt system and it includes new pullies. I assume this was because of the flat belt.Am I screwed up? Will a flat link belt work directly in place of a v belt? If so I can see going this route because I need to replace my drive belt.dusty wrote:Use a link belt.

No, they do make v-belts that are link belts, or link belts that are v-belts. 35 links is the number I found stated by Bill Mayo and a couple others, but I don't recall if they were the green or the orange belts - I think they have different length links (that's a tongue twiser!).
edit: I'd read that while both work - the green belts sold by harbor frieght and others and the orange powertwist belts - the powertwist are generally better and longer lasting. I don't have any experience with this, but I found powertwist belts for less, rather than the usual more, from zoro tools. They sell on ebay and directly. I think they only have 5 foot lengths so it was probably just cheaper because I needed enough for at least two.
Type A belts are what you want, as I recall, though you may want to confirm this.

Re: replacing lower Mark 5 belt with common automotive belt
one last...
Watch the video posted on the manufacturer's site showing how to connect and disconnect the links to change length shows a no longer young woman's hands with nail polish to match the belts EASILY adding and removing links. I KNOW they did that to keep people from publicly admitting that it's hard to do. It is. Not so much I'd avoid them but I know I can't do it that well:

um, yeah... no.

1/2 ". Realize they tend to increase wear on the sheaves.
Ideally a 9/16" belt is needed. A slight shift in speed range occurs with a belt narrower then 9/16". Ditto a length not = to 25.5".
Having spent some months getting(trying various lengths etc.) the correct belt for my Mark VII, I again recommend the mother ship(or a correct used one from e=bay).
Problem is, most '1/2"' belts are 12mm(less than 1/2") even though belt manufacturers state they are 13mm or more. They lie!!!!!!!!!
I am sure SS has to get a 'special' order to get the correct size. They tried 'typical' belts a while back with disastrous results. A few forum members can attest to that!
I think the Bandsawtirewarehouse belt on e-bay is 'correct'. 'HE' also makes a good poly-v belt FWIW.
